Hi,
Try to configure the channel-group only on physical interfaces and configure the trunking only on the port-channel interface.
Regard,

Soul,
try with "mode desirable" instead of "mode on". Cisco recommends mode desirable on both ends.
HTH,

Can someone tell me what I am doing wrong here? I am trying to accomplish lab1 in CCIE practical studies volume2.
Anytime I do the following configuration:
Interface FastEthernet0/1
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 1 mode on
!
interface FastEthernet0/2
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 1 mode on
I get the following errors message:
17:59:05: %STANDBY-3-DUPADDR: Duplicate address 172.16.200.16 on Vlan200, sourced by 0000.0c07.acc8

17:59:32: %LINK-3-UPDOWN: Interface Port-channel1, changed state to down
17:59:32: %LINK-3-UPDOWN: Interface FastEthernet0/2, changed state to down
I am using one CAT 3550 and 2950.
I shut one port either F0/1 or F0/2 I get no errors and everything work fine.
Any advice will be appreciated.
Thanks,
Soul
